When I do a run up and check the ignition at 2000 rpm there is no drop in rpm either left or right. Is this normal? BOB - ________________________________ Message 2 _____________________________________ Time: 03:44:18 PM PST US Subject: RE: JabiruEngine-List: Re: Ignition check [SEC=UNCLASSIFIED] From: "Sweeting, Ian MR" UNCLASSIFIED Bob, Try it at a lower RPM, say 1600. You could expect only a slight drop (eg <50RPM) which may not be perceptible at 2000. Ian.
